Branch Offices

A building represents a collection of facilities scattered across a world that create jobs that generate different kinds of resource that are not suitable to large-scale resource gathering. They are limited by the planet's population and capped to 16 buildings at 75 pops, with the first slot always being occupied by the colony's capital building. Each additional 5 pops unlock a new building slot.

If the number of pops falls below the number required for a building slot any constructed building will become ruined and stop producing jobs. Ruined buildings can be rebuilt for half the time and cost of a new one. If a planetary population is completely wiped out (either by resettlement or warfare), all pre-existing buildings will be completely destroyed.

Planet build speed

Planet Build Speed is a modifier that lowers the building time for all buildings. This modifier can be very useful, as it also affects building upgrades, and higher level buildings can take longer to build.

Capital

The Colony Capital always occupies the first building slot and provides some of the basic housing, amenities, jobs that reduce crime and spawn defence armies, and other jobs which vary depending on empire authority and civics. Many other buildings require a sufficiently high-level capital building before they can be built or upgraded, which gates your colony's development. Capital buildings cannot be demolished, downgraded, ruined, or disabled.

Standard capitals

The standard set of capitals are built on planets without a special designation as well as ringworlds by authorities. The base capital provides Colonist jobs that produce food and amenities to assist with the initial upkeep of a newly settled colony, which are removed upon upgrading.

Special colony types

Habitats and planets designated as Resort Worlds or Thrall Worlds have special capital types that replace the default ones.

Hive Mind capitals

Hive Mind empires only have two capital buildings. They are the equivalent to Tier II and Tier III capitals of other empires for conversion purposes, and the upgraded capital counts as Tier IV for requirements.

	Capital	Produces	Jobs	Upkeep	Cost	Description & Requirements
	Hive Core	Housing: +8 Amenities: +8	Hunter-Seeker Drone: +1 Synapse Drone: +2 Maintenance Drone: +2 Base Job output: +10 +8 +7 +2 −20	−2	None	The organizational core from which the Hive Mind coordinates planetside functions.

Colonial Centralization technology ≥40 pops

Machine Intelligence capitals

Machine Intelligence empires use buildings similar to regular empires and will convert to or from them if a planet is conquered by an empire with different authority. The number of jobs offered depends on whether the empire has the Driven Assimilator civic.

Buildings

Each regular building has up to 3 tiers, which determine its number of Jobs, upkeep, construction time and cost. Tier II and III buildings also require a certain strategic resource for construction and upkeep.

If a world is conquered by an empire that uses a different set of buildings for the same primary resource the existing buildings will be converted into new ones of the same tier.

Housing

Housing buildings provide Housing and come in two tiers. The advanced resource used to upgrade their tier is Rare Crystals. If the world is conquered by an empire with different government each housing building will be converted into the equal tier counterpart of the new owner.

Military

Military buildings produce defense armies and are vital for the protection of a world. Once constructed they will always be placed at the top of the buildings order to be the last buildings destroyed by orbital bombardment. Fortresses can also contain an FTL inhibitor if the FTL Inhibition technology has been researched. Upgrading Strongholds into Fortresses requires the Global Defense Grid technology.

	Building	Produces	Jobs	Upkeep	Cost	Description & Requirements
	Stronghold	Housing: +1	Soldier / Warrior Drone: +1	−1	600 240	A planetary stronghold housing a substantial garrison force to protect the world from invasion and rebellion.

Refineries

Refinery buildings produce advanced resources. Unlike the planetary feature buildings, they require mineral upkeep to produce them.

	Building	Jobs	Upkeep	Cost	Description & Requirements
	Chemical Plants	Chemist / Chem-Drone: +1	−3	500 480	The unpredictable and sometimes unstable Volatile Motes are produced here artificially. No open flames are permitted within a five kilometer radius of the plants. Volatile Material Plants technology
	Exotic Gas Refineries	Gas Refiner / Refinery Drone: +1	−3	500 480	These advanced refineries work day and night to produce exotic gases. Exotic Gas Refining technology

Whispers in the Stone archaeology site

Trade

Trade Buildings create Clerk and Merchant Jobs, which generate Trade Values and Amenities. While Clerk Jobs have a poor yield of only 2 Trade Value per Jobs, Commerce Buildings provide a significant number of them. Upgrading Commercial Zones into Commercial megaplexes requires the Interstellar Economics technology.

Gestalt Consciousness empires do not have civilian trade and cannot build these buildings. They also cannot be built on Thrall-Worlds.

	Building	Jobs	Upkeep	Time	Cost	Description
	Commercial Zones	+5 Clerk	−2	360	400	These commercial zones are home to towering office buildings and business complexes.
	Commerce Megaplexes	+10 Clerk +1 Merchant	−5  −1	480	600 50	Great commercial spires and towers rising up towards the sky, blotting out the light.

Organic safekeeping

Rogue Servitor empires need Organic safekeeping buildings to provide Bio-Trophy Jobs for Unity. These buildings are converted into Housing buildings of equal tier if the planet is conquered by an empire that lacks the civic. Upgrading Organic Sanctuaries to Organic Paradises requires the Idyllic Architecture technology.

	Building	Jobs	Upkeep	Time	Cost	Description
	Organic Sanctuary	Bio-Trophy +10 Maintenance Drone +1	−2	360	400	This sanctuary provides a sealed environment where organics can thrive in a safe and above all controlled manner.

Feature-related

Feature buildings can only be built based on the number certain rare Planetary Features allow.

	Building	Regular output	Gestalt Consciousness output	Upkeep	Time	Cost	Required technology	Planetary feature	Description

Fallen empire

Fallen Empire buildings are found on the homeworlds and planets of Fallen Empires. These buildings use incredibly advanced arcane technology, and as such are exceptionally effective compared to regular empire buildings. Most are autonomous, and can be used by other empires if captured. Ruined Fallen Empire buildings can be repaired. Fallen Empires, awakened or not, can never build more Fallen Empire buildings (with a few exceptions), making these buildings highly valuable.

Using the Reverse-Engineer Arcane Technology artifact action has a small chance to allow the user to build a Fallen Empire building on one of their planets. Each building takes 480 days to construct. If demolished however, they cannot be rebuilt.
